Abstract: The basic approach of this paper considers the blast weapon effects by simulations and experimental research. Silencer of weapon blast is considered as the acoustic dumping transformer and wave conductor. The basic approach of simulation uses directed acoustic point source model. A convenient method for describing the outputs creation of wave transformer is decomposition approach. The electrical acoustic analogies are also used in simulation model. The simulation and experimental results are tested and compared, showing good results agreement and proving accepted approach.

Keywords: silencer, simulation, decomposition approach, electrical acoustic analogies.
